Crime in Greece is combated by the Hellenic Police and other agencies.
During the 1980s, Greek Police Chief Nikon Arkoudeas (Νίκων Αρκουδέας) led an intense campaign against organized crime, which saw significant success. Since the early 1990s, many illegal immigrants have come to Greece from Eastern European and Southeast European countries, Africa and South Asia.
The Greek Police also had several victories, breaking up mafia organizations, arresting the 17 November terrorist group, successfully organizing security for the 2004 Olympic Games and for breaking up in 2016 the largest criminal organization in the country, responsible for more than 2,000 robberies.
Crime by type
Murder
In 2011, Greece had a murder rate of 1.7 per 100,000 population. There were a total of 184 murders in Greece in 2011.
Organized crime
Organized crime in Greece is on the rise. Domestic as well as foreign criminal groups are well-entrenched in Greek society. Traditionally, people associated with organized crime were known as Men of the night (άνθρωποι της νύχτας). Out of the foreign criminal groups the Albanian mafia is the most prevalent. The activities of the Albanian crime groups in Greece include drug trafficking, human trafficking, extortion and robbery among others.
Albanian criminal groups often export other immigrants to Greece, especially Middle Eastern and Pakistani shopkeepers, and control many nightclubs in the working-class districts of West Athens. Russian groups are less numerous, but they are very heavily armed and dangerous; they are involved in arms trafficking, extortion and cigarette smuggling. Lower-level Romanian and Moldavian groups are involved in theft and human trafficking.
Domestic, ethnic Greek criminal organizations are the most powerful and politically well-connected and extensively cooperate with Albanian groups, often hiring Albanians to act as enforcers. Greek criminal organizations are involved in human trafficking, extortion, drug trafficking, kidnapping and the infiltration of legal businesses. They have profited from the rising corruption. That is evident in the fact that Greek crime groups have infiltrated the shipping industry, which is used to traffic cocaine and heroin into the Greek mainland and abroad.
Property crime
As of 2011, Greece has seen an increase in property-related crime, thought to be linked to the worsening of economic conditions. Robberies, ranging from street muggings to bank hold-ups and house burglaries, totaled about 80,000 in 2009, up from about 50,000 in 2005. The increase in property crime has seen an increase in the amount of work for private security companies. Nevertheless, the crime rate is still among the lowest in Western Europe.
In 2016, the Greek police successfully broke up the country's largest criminal organization in Greece's history, which was responsible for more than 2,000 house burglaries across the country, in an operation where at least 1,000 policemen and 37 judges participated.
Immigrant crime
The Greek police have admitted that armed gangs entering the country from neighbouring Albania or Bulgaria could have been attracted by reports that many people have been withdrawing cash from banks and stashing it in their homes. There are possibly more than 1 million illegal immigrants inside Greece as of 2012. Cases of immigrant crime such as the 2012 Paros rape have attracted nationwide interest.
Illegal immigration to Greece has increased rapidly over the past several years. Tough immigration policies in Spain and Italy and agreements with their neighboring African countries to combat illegal immigration have changed the direction of African immigration flows toward Greece. At the same time, flows from the Arab world and South Asia — mainly Afghanistan, Algeria, Iraq, and Pakistan — to Greece appear to have increased as well.
The evidence now indicates that nearly all illegal immigration to the European Union flows through the country's porous borders. In 2010, 90 percent of all apprehensions for unauthorized entry into the European Union took place in Greece, compared to 75 percent in 2009 and 50 percent in 2008.
In 2010, 132,524 persons were arrested for "illegal entry or stay" in Greece, a sharp increase from 95,239 in 2006. Nearly half of those arrested (52,469) were immediately deported, the majority of them being Albanians.
